Again, less gratuitous changes from older versions (although it's still
different). Also more consistent with generated markup from indented code
blocks.

Because code blocks are added in sections, a nested section could be
unindented too far. Code is unindented in the main quickbook actions, so
there's actually no need to do it when extracting code snippets.
But this lead to left over whitespace that would have been stripped. So
change the `start_snippet` and `end_snippet` grammars to swallow up the
line they're on.
I also added a newline before the end of the snippet, this cleaned up
the occasional syntax error.
But due to these changes there is more leading and trailing whitespace
in the generated code blocks, so I just changed the code block grammar
to strip them out. This means there are no newlines at the beginning or
end of code blocks, but that should be fine.
